This is a souvenir trilby style straw hat that was sold at Expo 67, Montreal’s World Fair, held in 1967.  The hat is embroidered with the original owner’s name “Alexander” and has an Expo 67 Montreal Canada sticker applied to the front.  It is unsized but would fit a boy’s head - it measures 19 1/2” around the opening.  The hat is in very good condition, with no cracking to the straw, soiling or other defect.  This is a fun Expo 67 collectible hat - not a lot of these would have survived from 1967!
